jquery插件开发
/****************************************************\
* jQuery的插件开发机制分为两种：类级别的插件开发、对象级别的插件开发
*
* 类级别的插件开发：添加新的全局函数;使用$.extend(obj);使用命名空间;
* 添加全局函数：jQuery.plugin = function(){}
* 使用$.extend(obj):$.extend({
* plugin:function(){
*
* }
* });
* 调用方式为：$.plugin()
*
* 使用命名空间:jQuery.plugin = {
* plugin:function(){
*
* }
* }
* 调用方式为：$.plugin.pluginType()
*
* 对象级别的插件开发(常用方式):;(function($){
* $.fn.plugin = function(){
*
* }
* })(jQuery)
* 调用方式为：$(element).plugin();

准备好基本架构
;(function($){
var Carousel = function(poster,setting){
console.log(setting);
};
//给目标函数添加方法
Carousel.prototype = {

//初始化页面方法
Carousel.init = function(posters,setting){
var _this = this;
posters.each(function(){
//当前的this是DOM节点对象，通过$(this)包装成整个对象
new _this($(this),setting);
});
}
//因为在匿名函数内部，需要全局注册后外部才可以调用
window['Carousel'] = Carousel;
})(jQuery);HTML
